Removing Category Base from WordPress URLs

I received the following from James, basically requesting information on how to remove the /category/ base from WordPress urls.

Hey, man. Spent quite a while on the site and i’m still having an issue with this, so i’ll give it a go with you. We’re using WP as a CMS with pages and posts. Done a bit of customization, so it looks sweet. Problem – i have some child categories that throw 404 when the category redirect is in place. How did you remove the category base from the url structure in wordpress? This has really got me going… thanks for being accessible!
This was one of the first hacks I figured out for WordPress, so if anyone has an improvement…

WordPress Modifications ^

It’s very important that you replace all the links on your site to /category/slug/ to /slug/ or you will have problems. These steps should only take you a few minutes.

Removing /category/ Automatically ^

This is the main hack to make it work automatically throughout your site. You can place this code in your themes functions.php folder, or you can stick it in a plugin file.

function fix_slash( $string, $type )
{
global $wp_rewrite;
if ( $wp_rewrite->use_trailing_slashes == false )
{
if ( $type != ‘single’ && $type != ‘category’ )
return trailingslashit( $string );

if ( $type == ‘single’ && ( strpos( $string, ‘.html/’ ) !== false ) )
return trailingslashit( $string );

if ( $type == ‘category’ && ( strpos( $string, ‘category’ ) !== false ) )
{
$aa_g = str_replace( “/category/”, “/”, $string );
return trailingslashit( $aa_g );
}
if ( $type == ‘category’ )
return trailingslashit( $string );
}
return $string;
}

add_filter( ‘user_trailingslashit’, ‘fix_slash’, 55, 2 );
category.php Theme Modifications ^

Here’s one way to fix the url in the category.php file of your wordpress theme.

<h1><a href=”http://www.askapache.com/&lt;?php echo str_replace(‘ ‘,’-‘,strtolower(single_cat_title(“”, false)));?>/”><?php echo single_cat_title(“”, false);?></a></h1>

.htaccess Modifications ^

The below .htaccess code illustrates 2 different ways to redirect any request for /category/slug/ to /slug/. You should only redirect after applying the php hacks described earlier, otherwise you could end up creating a loop.

RedirectMatch 301 ^/category/(.+)$ http://www.askapache.com/$1
# OR
RewriteRule ^category/(.+)$ http://www.askapache.com/$1 [R=301,L]
That’s it!

How To Use These Snippets
If you wanted to move the Thesis Nav Menu below the Header:

First, remove the Nav from the hook, “Before Header”

remove_action( ‘thesis_hook_before_header’, ‘thesis_nav_menu’ );
Now, add it back to the hook, “After Header”

add_action( ‘thesis_hook_after_header’, ‘thesis_nav_menu’ );
The final syntax in custom_functions.php would look like this:

remove_action(‘thesis_hook_before_header’, ‘thesis_nav_menu’);
add_action(‘thesis_hook_after_header’, ‘thesis_nav_menu’);

Permalink trong wordpress, để permalink hoạt động trên localhost

Trong viết blog hay website người ta lun coi trong việc sử dụng permalink (URL thân thiện) và nó là một điểm đáng lưu tâm của người làm SEO. Hôm nay chúng ta sẽ kích hoạt nó chạy được trên localhost.
Permalink là gì?

Permalink là một tính năng của WordPress nó giúp ta tối ưu địa chỉ của trang web (URL). Một url thân thiện, gợi nhớ sẽ rất tốt cho người dùng cũng như các công cụ tìm kiếm đễ dàng hơn trong việc hình dung ra nội dung của trang web bạn mún nói gì. Thay vì phải truyền truy vấn như: http://bcdonline.net/?p=1 thì bây giờ có thể sẽ dễ thương hơn khi có URL: http://bcdonline.net/bancamden/.
Sử dụng Permalink trong WordPress

Để có một URL thân thiện bạn nên không để tiếng Việt có dấu trên url của mình, vì có nhiều lý do, dễ dàng nhầm lẫn, làm phức tạp chuỗi địa chỉ, không trong sáng… để làm điều này trong WordPress cũng hỗ trợ cho bạn.

Khi post bài bạn sẽ custom lại chuổi url của mình bằng cách như sau:
Permalink new post

Permalink new post

Bạn nhìn thấy trên hình, nhập vào chuổi địa chỉ bạn muốn hiển thị vào OK.

Bây giờ chúng ta sẽ sử dụng tính năng Permalink, bạn vào admin control của WordPress trong menu settings chọn vào permalink. Và thực hiện như sau:
Sử dụng tính năng permalink trong wordpress

Sử dụng tính năng permalink trong wordpress

Đến phần quan trong rồi đây trong này có nhiều vấn đề cần nói. Kiểu mặc định của nó là giá trị nguyên thủy bao gồm ID mà thôi, kiểu thứ hai cho phép hiển thị ngày tháng năm vào kèm theo là ten của bài viết, Kiểu thứ ba là năm tháng rồi tên bài viết, kiểu thứ tư là tên bài viết đến ID.

Tiếp đến kiểu thứ năm là tùy chọn, cho phép bạn nhập chuỗi hiển thị, trong WordPress cung cấp cho chúng ta có các chuỗi hiển thị như sau:

/%postname%/: hiển thị url bao gồm tên mà thôi ví dụ: http://bcdonline.net/lien-he/. Blog mình cũng đang xài kiểu này.
/%postname%.html: bạn cũng có thể thêm vào sau đó là đuôi .html hay một đuôi mở rộng nào đó tùy ý. Ví dụ: http://localhost/wordpress/bcdonline.html
/%category%/%postname%/: tên thể loại và sau đó là tên bài viết thuộc thể loại đó. Ví dụ: http://localhost/wordpress/bcdonline-net/bcdonline/
Và còn nhiều thành phần khác nữa.

Ngoài ra bạn cũng thấy ở hình trên có hai thành phần nữa là category base và tag base.

category base: Qui định hiển thị tên chung của thể loại hay chủng loại gì đó, mặc định là category.
tag base: Qui đinh hiển thị tên chung của từ khóa, mặc định là tag.

Để Permalink làm việc trên localhost

Sau khi đã làm các công việc trên đối với những ai xài appser hay wamp thì vẫn chưa xong đâu vì chạy trang index dc nhưng click vào các trang chi tiết bài post thì báo lỗi 404 (Not Found).

Để khắc phục tình trạng này bạn thực hiện như sau: Vào trong thư mục của E:\AppServ\Apache2.2\conf\httpd.conf tùy vào địa chỉ bạn vài đặt nha! mở file đó lên tìm đến dòng có chữ:
1

#LoadModule rewrite_module modules/mod_rewrite.so

Bạn bỏ dấu # ở trước đó đi, với wamp thì bạn tìm thêm dòng:
1

# Controls who can get stuff from this server.

Bạn tiến hành khởi động lại Apache của server lại và test thử.

Kết luận: Vậy là mình đã giới thiệu cho các bạn cách sử dụng permalink và custom permalink trong wordpress và phương pháp để nó hoạt động trên localhost. Chúc thành công!

WordPress Error – “Allowed memory size of 8388608 bytes”

You sometimes might get the following error if you are trying to import a previous blog into a newly installation of WordPress through an RSS feed or while installing a new plugin as:

Allowed memory size of 8388608 bytes exhausted (tried to allocate xxxxx bytes)

This means that the server is not allowing to process the size of the data than its maximum alloted size. Remember that there is nothing wrong with the WordPress installation. Its the matter of the amount of data that the server can process at one time.

Don’t be scared, you can get it resolved in a matter of seconds. There are two ways of resolving this error.

Method #1 : Without Restarting the Server

If the error mentioned appears during the importing, what you need to do is get access to the source code of the WordPress where you have done the installation.

Once you get the access you will need to modify two files . They are:

  1. <installation_directory>/wp-admin/import.php
  2. <installation_directory>/wp-admin/import/wordpress.php

Now copy this line of code:

ini_set('memory_limit','16M');

This line increases the server processing capacity by the included size i.e 16M. Paste the above line in the import.php file just after the line of code:

require_once ('admin-header.php');

Now in the second file i.e. wordpress.php paste the code after the line of code:

<?php

Note: If the error mentioned appears during the installation of a plugin then make a note of the path and the .php page which is given out in the error and paste the same line in the mentioned .php page.Remember, the code must be pasted within the php code block i.e in between <?php and php?> in the page since it is to be executed by the server.

Now once again access your WordPress URL and go to the manage > import menu and try importing. If your problem still remains, just keep increasing the size mentioned in the pasted code in multiples of 4 i.e. in place of “16M”, try “20M”, “24M” etc.

Method #2 : Which Requires a Server Restart

If you want to eliminate this error once and for all then you need to target your server to make the changes. But you should have the permissions to restart the server.

If you have this permission then go to the server installed path and search for the file php.ini file. In this file there will numerous things mentioned. But all you have to do is search for the term “memory_limit“. Change the value of this variable from 8M to either 16M, 24M, etc as required.

Save the file and restart your server. The error will be resolved once and for all. Good luck!

Add New Hook In Prestashop

PrestaShop hooks are great way to insert or add data at the most important places or actions of this great e-commerce platform. But may be some time you want to use custom hooks with my custom modules. So here I show you how to implement custom hook?


How to create custom hook?

Step 1: Register a new hook in FrontController.php

open file \classes\FrontController.php and find below code

1
2
3
4
5
self::$smarty->assign(array(
'HOOK_HEADER' => Module::hookExec('header'),
'HOOK_TOP' => Module::hookExec('top'),
'HOOK_LEFT_COLUMN' => Module::hookExec('leftColumn')
));

Updated code

For add new hook I add this line of code

1
'HOOK_Top_Center' => Module::hookExec('topCenter') // New Hook

So you code look like below.

1
2
3
4
5
6
self::$smarty->assign(array(
'HOOK_HEADER' => Module::hookExec('header'),
'HOOK_TOP' => Module::hookExec('top'),
'HOOK_LEFT_COLUMN' => Module::hookExec('leftColumn'),
'HOOK_Top_Center' => Module::hookExec('topCenter')
));

Step 2: All active hooks are hold in Prestashop database table called ps_hook. So I make query for new hook and run into database.

1
2
3
4
5
6
7
8
9
10
INSERT INTO 'yourdatabasename'.'ps_hook' (
'id_hook' ,
'name' ,
'title' ,
'description' ,
'position'
)
VALUES (
NULL , 'topCenter', 'Top of Center', NULL , '1'
);

What are field mean ps_hook.

`id_hook` = An auto increment value
`name` = Name of the new hook
`title` = This title is used in Modules tab in Back Office
`description` = The description of hook (optional)
`position` = Whether this hook observe the order of appearance with other module or not

Or you can add value manually from php myadmin.

open your “php_myadmin” and table “ps_hook” click on “insert” and insert ‘new’ hook name, ‘new hook’ in ‘title’

Step 3: Add code in your module:

Please create new function with name hooktopCenter in class of modules PHP file which you want to use.
‘hook’ is prefix function for hook
‘topCenter’ is name of hook postion

Here I call blockmanufacturer.tpl file in this funcation.

1
2
3
4
5
6
7

10
11
12
13
function hooktopCenter($params){
global $smarty, $link;
$smarty->assign(array(
'manufacturers' => Manufacturer::getManufacturers(),
'link' => $link,
'text_list' => Configuration::get('MANUFACTURER_DISPLAY_TEXT'),
'text_list_nb' => Configuration::get('MANUFACTURER_DISPLAY_TEXT_NB'),
'form_list' => Configuration::get('MANUFACTURER_DISPLAY_FORM'),
'display_link_manufacturer' => Configuration::get('PS_DISPLAY_SUPPLIERS'),
));
return $this->display(__FILE__, 'blockmanufacturer.tpl');
}

Step 4: Add the code {$HOOK_Top_Center} in theme/prestashop/header.tpl or any other tpl file where you want to use it.

1
<div id="header_right"> {$HOOK_Top_Center} </div>

Step 5: Then go to backend
=> Click on module top of link and configure any module which you want to change position and show in you new hook position.
=> Click position
=> Click on transplant module and select “topCenter” from dropdown and save.

Than look at your frontend at that position.

Add widget to wordpress theme

We can add widget to wordpress theme ( any where: sidebar,footer,content page,…)

In this example, I will guide you add widget to wordpress theme.

There are really three main parts to introducing a footer-sidebar
1. Registering the Sidebars in the WordPress Theme
2. Inserting the Sidebars In the WordPress Theme
3. Putting some style into the sidebars

1. Register the Sidebars in the WordPress Theme

Go to the WordPress theme editor and open the Theme Functions (functions.php) file. Now Search for the following line in your Theme Functions (functions.php)

if ( function_exists('register_sidebar') )

Once you find the above line then take a look at the the next line which should look similar to one of the followings depending on how many sidebars you have:

register_sidebar(array(
or
register_sidebars(2,array(

Say for example you have one sidebar in your theme and you want to add three rows of sidebars in the footer area so you can put widgets then overwrite the code with the following:

register_sidebars(4,array(

The above will register 4 sidebars (one that you already have and three more that you are about to introduce in the footer area of your wordpress theme).

2. Insert the Sidebars In the WordPress Theme

Now lets insert the siderbars where we want them in the WordPress theme. In our case we are going to insert in in the footer area of the theme so open the Footer (footer.php) file and insert the following code just above the ‘footer’ division:

<div id="footer-sidebar">
<div id="footer-sidebar1">
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar(2) ) : ?>
<?php endif; ?>
</div>

<div id="footer-sidebar2">
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar(3) ) : ?>
<?php endif; ?>
</div>

<div id="footer-sidebar3">
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar(4) ) : ?>
<?php endif; ?>
</div>

</div>
<div style="clear-both"></div>

3. Put some style into the sidebars

Finally, lets put a little style to all the ‘footer-sidebar’ divisions that we just introduced. Open the Stylesheet (style.css) file and insert the following CSS (you will probably have to adjust the CSS to your need depending on what wordpress theme you are using).

#footer-sidebar {
display:block;
height: 250px;
}

#footer-sidebar1 {
float: left;
width: 340px;
margin-left:5px;
margin-right:5px;
}

#footer-sidebar2 {
float: left;
width: 340px;
margin-right:5px;
}

#footer-sidebar3 {
float: left;
width: 340px;
}

Hope this helps! Now you don’t have to change your beloved WordPress theme just to get footer-sidebar :)

Get taxonomy in wordpress

Today, I post about the way to get taxonomy in wordpress:
1-Get the taxonomy name by query_var

$the_tax = get_taxonomy( get_query_var( ‘taxonomy’ ) );
echo $the_tax->labels->name;

Get

if (is_archive())
{
if(is_tax(‘destination’))
{
$term = get_term_by( ‘slug’, get_query_var( ‘term’ ),            get_query_var( ‘taxonomy’ ) );

Get the description:
echo $term->description);

or use this:

$description = explode(“|”, $term->description);
$dest1= $description[0];
